System paging delay plot
SRM uses the system paging delay plot to determine if the paging configuration is close to capacity or if it can support additional work. There is one system paging plot per system. The plot can show the point at which additional page faults will start requiring a disproportionately longer time because the paging subsystem is becoming overloaded.
- x axis
- The system wide page fault rate, in page faults per second.
- y axis
- The system wide auxiliary storage delay sample rate, in samples per minute.
Page faults and delay samples are for all types: private area, common area, and cross memory.
The system paging delay plot is recorded in subtype 1 records.
